AIM To evaluate the role of biofilm formation on the resistance of Helicobacter pylori (H. pylori) to commonly prescribed antibiotics, the expression rates of resistance genes in biofilm-forming and planktonic cells were compared. METHODS A collection of 33 H. pylori isolates from children and adult patients with chronic infection were taken for the(More)
BACKGROUND/AIM Despite the significant number of studies on H. pylori pathogenesis, not much data has been published concerning its ability to form biofilm in the host stomach. This study aims to evaluate the potential of clinical isolates of H. pylori to form biofilm in C57BL/6J mice model. MATERIALS AND METHODS Two strains of H. pylori were selected(More)
BACKGROUND During the last decades the rate of multidrug resistance among clinical Helicobacter pylori isolates has increased. Active pumping out of the drugs may be an important mechanism for multidrug resistance in H. pylori strains. OBJECTIVES The aim of this study was to evaluate the association of two H. pylori efflux-genes, hp1181 and hp1184 with(More)
